CAN-SOLDERING MACHINE.

SPECIFICATION forming part of .Letters Patent No. 263,598, dated August 29, 1882,

Application filed January 21, 1881. (No model.)

To all whom it may concern:

Beit known that I, FREDERIcK W. SCHULTZ, a citizen of the United States, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Can Soldering Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to can-soldering machines of that class in which the head-seam is soldered by inclining the can and rotating it While the head-seam is immersed in a molten solder bath.

The construction of the apparatus embodying my invention will first be described and its operation explained, and then the parts and combinations which I claim as my invention will be designated.

In the drawings which are hereto annexed, Figure 1 is a side elevation of the apparatus. Fig.2 is a top plan of the can-holder. Fig. 3 is a view transverse to that shown in Fig. 1 of the inclined standard. Figs. 4 and'5'are sectional views of the soldering device.

The letter A designates the stand to which all the parts are attached.

B designates a frame, preferably rectangular in shape, which carries the rotary can-holder consisting of the two disks 0 c. The first has a flange to encircle one end of the can, as shown in Fig. 1, and the last is without a flange, and is smaller than the cylinder of the can, and is intended to bear against the canhead, as shown.

It will be seen the flanged disk operates to center the cylindrical can' at one end with respect to the axis of rotation of the can-holder,

while the other end of the can; takes position against the smaller and flangeless di'skjust as may happen-that is, concentrically or eccentrically. The disk 0 is swiveled to the fixed spindle d, (shown in Fig. 2 in section,) while the disk 0 is secured rigidly in any suitable manner to the shaft 0, which is capable of both a rotating and an endwise-sliding movement through the bearin gs f. A collar, 0, is secured center to contain the solder.

to the shaft, and a spiral spring, g, surrounds the shaft between the collar and the upper hearing. The effect of this spring is to keep the disk 0 pressed toward its coacting disk, and thereby adapt the two to clamp the can endwise. The outer end of the shaft is provided with a hand crank, it, by which the can is rotated.

The can-holding frame B has on two opposite sides a trunnion or pivot, I), each of which has bearing in a vertical standard, I, between which the frame is supported. The trunnions permit the frame and can-holder to be tilted for a purpose hereinafter explained. The standard I is provided with a vertical slot, through which the trunnion 1) passes, and an adjustable plate, I, having a hole for the trunnion, and slots k are secured to the plate I by set-screws passed through the slots. By means of these vertically-adjustable standards the can-holding frame may he raised or lowered to adapt it to carry either alarge or small can.

The soldering device consists of an iron, L, having a receptacle, n, extending down its In size the solderreceptacle is much broader in one direction than the other, as indicated in Figs. 4 and 5. The top of the iron in the broad direction is ooncaved, as shown at S, Fig. 4, to correspond with the cylinder of the can, and is provided with a groove extending across the top in the broad direction of the iron, and the upper end of the solder-receptacle opens into the groove.

A vertical tube, L, stands at one side of the soldering-iron, and has its lower end connected with the lower end of the solder-receptacle n. This constitutes the solder-supply tube, as will hereinafter'be explained.

A stop, 19, consisting of a set-screw, has a vertical adjustment, and serves to regulate the relative position of the lower head-seam of the inclined can with respect to the solderingiron, so as to allow the head-seam to bear on the iron with greater or less pressure, as desired; but the stop device also serves another purpose-namely, to stop the tilting frame in such position that the axis of the flangeless disk will be so distanced from the top of the solder-applying device that the lower head of the inclined can will, by its edge turning in contact with the solder-applying device, assume a concentric position in the flangeless disk. To this end the stop is placed so that one end of the tilting frame B will strike the top of the stop, as shown in Fig. 1. A spring, g, is attached to the other end of the frame and to a cross-rod (not shown) at the top of the two standards B. This spring serves to lift the said end of the frame, and of course depresses the opposite end, and therebyinclines the can, bringing the seam of one head in contact: with the solder-iron. In this position the can-holder is rotated by means of the crank, and the head-seam of the can is turned in contact with the concaved and grooved upper end of the soldering-iron.

The heretofore-described shape of the iron provides that the flange of the can-head may bear in a groove and the cylinder next to the flange of the head bear on the side edge at the top of the iron. Thereby theiron imparts its heat to both the can head and body, and at the same time the molten solder, which fills the receptacle brimful to the groovein the top of the iron, flows into the seam.

dering-iron.

The lower end of the can-holder frame has a boss or thickened part, t, through which a setscrew passes. The inner end of the setscrew forms the seat for the end of the diskshaft (7. By means of the set-screw the candisk 0 may be adjusted to or from its coacting disk.

An inclined plate, M, is secured in any suitable manner so that the inclination shall extend outward or away from the can-holding frame from the upper to the lower end of the plate. In the drawings the lower end of this plate is connected with an arm, M, the two forming an elbow-shaped standard. The arm is secured to the stand A. This inclined plate is slotted, as seen at a, Fig. 3, and the can-disk shaft 0 is passed through the slot, and has on its extremity the head of the crank h. This construction and combination of parts serve, when the can-holder is tilted up and the crank end of the can-holding frame is tilted down, to withdraw the shaft-disk c from the end of the can, and thereby release the can or permit another can to be placed between the two endwise-clamping disks.

A wire or rod, '12, is attached to the upper end of the can-holding frame, and extends to the floor, where it connects with a foot-treadle, W, by means of which the can-holder may be raised to take out or place in a can.

A burner, Y, adapted to produce aheatingflame of the Bunsen description, is secured in position adjacent to the solderingiron. so as to play its flame horizontally against the sol- The particular position of the burner or the direction in which the flame plays is, however, a matter of not much consequence. The heat of the flame will keep the solder contained both in the supply-tube and in the receptacle ot' the iron in a molten condition. In practice the receptacle in the soldering-iron is kept full by the operator occasionally dropping a small piece of solder into the supply-tube. The burner is supplied with hydrocarbon fluid-such as gasoline-which is fed to it in any suitable manner, as by elevating the tank containing the fluid so that the latter will flow by gravity.

Having described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a can-soldering machine, the combination of a device by which solder is applied, a rotary can-holder having a disk smaller than the cylinder of the can to bear against the end of the can, a tilting frame carrying the canholder, and an adjustable stop device against which the tiltingfranie may strike to regulate the position of the small disk with respect to the solder-applying device, as set forth.
